An assessment of the role of green belts in creating comfortable microclimatic conditions in summerAbstract
Against the background of global warming and a decline in urban vegetation, they pose a danger of overheating in summer. In this article, we stress the significance of green spaces as a principal factor in reducing the overheating of urban surfaces. We analyse a high-rise residential area in the left-bank part of the city of Voronezh to perform a simulation of microclimatic conditions in summer. The following parameters were used as background climatic conditions: the day of the summer solstice, cloudless and calm weather, air temperature 25° C. We assessed the level of thermal comfort in the current landscaping situation in the residential area, taking into account proposed climate improvement initiatives, particularly, planting evergreen and deciduous trees. We evaluated the level of thermal comfort using the PMV index. In the current landscaping situation, the residential area studied is severely overheated. Our simulation, which allows for the effects of planted trees, shows a reduction in the PMV index in parks enjoyed by children and adults. The reduction is accounted for by a decrease in the average radiation temperature.
